Its hit/miss with that .. I don't know why .. maybe we need a new carrier.plist update ..

I got it working the first time, but couldn't receive from non-iphone sender .. so i tried the sinfulrepo .. that didn't work .. restore back to original settings and now it doesn't want to work anymore -_-

With the Edge sometimes working .. my solution is to activate MyWi to on then off .. Your edge should work right after.. My edge goes away everytime i reboot lol. So i just start MyWi everytime i reboot
